From my brief testing, the performance of the latest Intel drivers is significantly better than what shipped in 9.04. Now I'm running 9.04 with a new kernel, xorg edgers, and an old 855GM chip (so there are limitations :-) ) so it's far from what you are testing, but I think the Alpha status should be taken more seriously. Perhaps, as suggested in many places above, test the Intel drivers on another platform.

Like I ask on most of your articles, have you raised a bug for any of these regressions? Either on freedesktop or with ubuntu?

Also how do you know it's Mesa 7.5 that's the issue and not libdrm or the drm kernel driver?

MAybe if you spent some time talking to the developers on IRC and less time running the PTS some of these regressions would be fixed

Hope you reply to this

The author doesn't know. This article is completely mislabeled. It's comparing Ubuntu 9.04 to Ubuntu 9.10 alpha 3. No other conclusion can be drawn.

Way too many variables changed to know where the bottle neck is. It would be interesting to run the tests with versions 2.6, 2.7 of the intel drivers against the same Ubuntu 9.10 alpha 3 release. Then we'd know something.

From what I've heard on the Arch Linux forums is that 2.8 runs much faster on the 2.6.31 kernel than it does on .30.

From my experience on Arch with Linux 2.6.30, I get 850fps on glxgears with 2.7 and 550 with 2.8.

I haven't been able to try 2.6.31 on that system because I wasn't paying attention when I bought the laptop and I ended up with a broadcom wifi chip, and the driver from AUR doesn't support 2.6.31 yet.
